A cylinder head assembly for an internal combustion engine includes a cast cylinder head, a turbocharger housing including a compressor housing and turbine housing integrally cast with the cylinder head, and a turbocharger cartridge assembly configured to be inserted into the turbocharger housing and including a shaft coupled between a compressor wheel and a turbine wheel. A compressor cover is configured to couple to the compressor housing and define a compressor inlet and at least partially define a compressor diffuser passage. The cartridge assembly includes a housing having a diffuser flange extending outwardly therefrom, the diffuser flange including a front surface and an opposite contoured volute surface. The compressor diffuser passage is at least partially defined by the compressor cover and the diffuser flange front surface. A compressor volute is at least partially defined by the diffuser flange contoured volute surface and a contoured inner surface of the compressor housing.

Cylinder head with integrated turbocharger

A cylinder head assembly includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head. The integrated cylinder head and turbocharger housing includes: (i) a compact low wetted area to provide an uninterrupted flow path pointed directly at a catalyst face to facilitate achieving cold start emissions targets, (ii) a casting core assembly with specific core geometry and steps for assembly to enable core assembly while meeting all cylinder head and integrated turbine housing functional requirements, (iii) an oxygen sensor disposed pre-turbine in an integrated exhaust manifold, and (iv) a fully integrated PCV make-up air system.

An air induction system for a vehicle includes a turbocharger having a compressor side inlet and a bifurcated clean air intake system having a bifurcated conduit. The bifurcated conduit includes an upstream end configured to receive intake air, a downstream end configured to supply intake air to the compressor side inlet, an inner passage configured to supply intake air to the downstream end, and an outer passage disposed about the inner passage and separated from the inner passage by an inner wall, the outer passage configured to selectively receive recirculation backflow from the compressor side inlet. A port is fluidly coupled between the outer passage and another location of the vehicle. The port is configured to selectively evacuate at least a portion of the recirculation backflow to the another location the vehicle.

Bifurcated air induction system for turbocharged engines

A transmission includes a housing, a park gear, and a vehicle park shifting system configured to selectively engage the park gear to shift the transmission into and out of a park position. The vehicle park shifting system includes a linkage operably associated with the park gear, an actuator assembly operably coupled to the linkage and configured to be actuated to selectively move the linkage into and out of engagement with the park gear, and a lost motion manual shifter assembly operably coupled to the linkage and including a shift shaft disposed at least partially within the housing. The shift shaft is configured to couple to a manual park release system utilized to manually shift the transmission into and out of park without utilizing the actuator assembly. Actuation of the actuator assembly does not impart rotational movement to the shift shaft.

Lost motion transmission shifter

A vehicle transmission braking mode comprises determining a set of available clutches of the plurality of clutches that are not being utilized for engagement of a particular forward gear of the plurality of forward gears, determining at least one of a modeled temperature, a measured temperature, and a modeled energy of each clutch of the set of available clutches to obtain a set of at least one of clutch temperatures and energies, and based on at least the set of available clutches and the set of at least one of clutch temperatures and energies, selectively operate the transmission in the transmission braking mode by at least partially applying at least one clutch of the set of available clutches to mitigate or prevent powerflow through the transmission and thereby decrease or maintain a speed of the vehicle and/or reduce acceleration of the vehicle.
